Application filed December 13, 1923. Serial No. 680,457.

\ State of California, have invented new and useful Improvements in Solid-Tire Facers be quickly and unifo and Groovers, of which the following is a specification.

The invention relates to a device for dressin or facin solid rubber tires of vehicles.

t is an o ject of the present invention to provide .a means of racticable and substantial form, and by w 'ch a tire while in place on a wheel can be faced or dressed or grooved.

Another object is to provide a tire facm or grooving device whereby an elevate wheel of a vehicle carr ing a solid tire can rml y faced orsmoothed or'grooved.

. Another object is to provide a' facing device including a tool engageable with the tire to be faced, and to provide for the ready adjustment of the tool to tires of different diameters.

()ther objects and advantages will be madev manifest in the following specification of an, embodiment of the invention illustrated in the accompanying drawings, wherein Fig. 1 is a side elevation of the apparatus as in use. y

Fig. 2 is an end view with parts in section. Fig. 3 is a plan. The resent instrument includes a suitable and su stantial bed frame or latform 2, at one end of which is provide a .suitable motor M, by which isdrlven a cross shaft 3, as for instance by a pulley and belt 4.

The gfcross shaft 3 is 6 extending to sprocket wheel 7 secured on and driving a countershaft 8, which is preferablylmounted in adjustable boxes 9. Y

On the countershaft 8 is a cylindrical roller 10 which is parallel to another cylindrical roller 11 journaled on the frame 2 andrunning free. Y

The spaced rollers 10 and 11 are provided to receive .and'rotatably support the tire T which is to be facdor grooved and which may beoperated while in place on the wheel W of a vehicle V. When the motor is operating .power is transmitted to the roller 10 and this is driven and thereby the wheel W is rotated at a suitable rate of speed readily.

determined by a proper ratio of transmitting rovided with a sprocket wheel '5 engaged y sprocket chain means connecting the roller 10 and the motor. Cutting means includes any suitable style and shape of cutter C which is detachably connected to a slide 13 slidably mounted ina guide 14 extending transversely of the frame 2 and mounted on the upper ends of a pair of swinging arms 15, the lower ends I pivotally connected at 16 to the" of which are frame 2. r

The slide 13 has a threaded part 13 engaged by a feed screw 17 journaled in the upper ends of the arms 15 of the slide frame so that by turning the'said screw the cutter C may be advanced gradually transversely across the face of the tire T. Means are provided for advancing the cutter toward or retracting it from the tire and such means is shown as including a jack screw 18, the lower end of which is mounted in a stirrup 19, the ends of which are pivotally connected at 20 to the frame 2 so that the stirrup can terminate in a vertical plane. The open end of the jack screw engages a threaded part 21 of a frame 22, having divergent s1de arms which are pivotally connected at 23 to the upper portions of the slide frame arms 15. It will be seen that by turning the jack screw 18 by its handle 18, the frame 22 may be forced upwardly or retracted with a corresponding movement of the slide frame 15 so as to bring the cutter G into an en agemen't with or away from the tire T. T e jack screw 18 andits frame 22 provide not only a .means for advancing or retracting the cutter, but furthermore From the above it will be seen that I have provided a simple, practicable, and effective and substantial means for quickly facing or grooving a tire while the same is in place upon a wheel or vehicle.

' Further embodiments, modifications and variations may be resorted to within the principle of the invention.

What is claimed is:

1. A solid tire facer and groover comprising a bed frame, a motor mounted on one end of the bed frame, a cross shaft mounted on the bed frame substantially half way between the motor and the center of the frame,

means for connecting the motor to the cross shaft, a counter-shaft mounted onfthe bed frame near its center, means for connecting the cross shaft to the counter-shaft, a roller on the counter-shaft, a second roller parallel with the first roller and spaced therefrom Q 7 we 72 and mounted on the bed frame, said rollers adapted to engage the rotating tire, and a beingadapted to receive .and rotatab1y supjack screw connected to the bed frame and 10 port a tire to be operated upon, a pan of to the upper parts of the arms for swinging V arms-pivotally connected to the bed frame the arms to move the cutter to or from the I and extending upwardly, a slide mounted tire. upon the upper ends of the arm and adapted In testimony whereof I have signed my to move transversely, a screw for operating name to this specification. the slide, a cutter carried by the slide and BRUCE E.
